Frequently Asked Questions.

What are Hair Guru London fibres made of?

Our fibres are made from natural cotton using our proprietary CottonWrap™ technology. Unlike keratin-based fibres, cotton fibres naturally wrap around your existing hair strands for a denser, more undetectable finish. They’re plant-based, vegan, and gentle on even the most sensitive scalps.

How do I apply the fibres?

Application takes about 30 seconds. Shake the bottle gently over thinning areas, starting from the crown and working forward. Tap lightly to let the fibres settle, then finish with 4–6 light mists of our Locking Spray. For precision around the hairline, use our Easy Apply Fibre Pump.

Will people notice I’m wearing hair fibres?

No. Our cotton fibres are completely undetectable, even in bright sunlight and under close inspection. CottonWrap™ fibres blend seamlessly with your natural hair texture. Most of our 35,000+ customers tell us nobody can tell they’re using anything at all.

Are the fibres rain, sweat, and wind proof?

Yes. Once secured with our Locking Spray, Hair Guru fibres are resistant to rain, sweat, and wind. They’ll hold up through your gym session, a rainy commute, or a long day outdoors. The fibres stay in place until you wash them out with regular shampoo.

How do I choose the right shade?

We offer 14 shades to match virtually every hair colour. Use our free AI Colour Match Scanner — just scan your hair and get your perfect shade in 10 seconds. When in doubt, go slightly darker for the most natural result.

How long does one bottle last?

Our standard 28g bottle lasts most people 1–2 months with daily use. For lighter touch-ups, it can last even longer. We also offer a 100g Refill Pouch for better value and a 5g Sample Size to try before you commit.

Is it safe for sensitive scalps?

Absolutely. Our fibres are made from natural cotton with no harsh chemicals, synthetic dyes, or irritants. They’re dermatologist-friendly and safe for daily use, even on the most sensitive skin. The formula is also vegan and cruelty-free.

What is your returns policy?

We offer a 30-day money-back guarantee. If you’re not completely satisfied, contact us and we’ll sort it out. We also offer free shade exchanges if your colour isn’t quite right, and free replacements for any lost packages.

Love the kit format - great value and it all works together. - Only reason it's not 5 stars is because delivery took a bit longer than expected.

I was going back and forth with myself for about

I was going back and forth with myself for about a year whether to try it or not but I finally bought it just to try it and it’s actually brilliant! If you use the right amount and don’t over do it with putting the fibres in no one can tell a thing! If I put it on to go on a night out it’s still completely the same in the morning after being out all night and sleeping, it will only come out in the shower while using shampoo, honestly a life saver it’s saved me from shaving my hair off 😂

It makes you look younger and fitter!

I did a great deal of research into different fibres before deciding on Hair Guru London. I started losing my hair in my 30's and have been fortunate enough to turn back time by affording Harley Street hair transplants. Twenty years have passed since my first surgery (I have needed three so far) and yet again my hair is thinning. Rather than go under the knife again, I decided to look at fibres. I ordered fibres, the pump and the spray together, and purchased a hairline comb separately. Once I worked out how to attach the pump to the container (it is not obvious), and started to use the fibres after each hair wash, the result has been miraculous. The first day I went out, I was amazed at myself in shop windows, sporting the fullest head of hair I have had for years. I looked 10 years or more younger, and that is reason alone to do this. I wash my hair every few days. One application after washing stays in for several days. They do not come off on your pillow or clothing and are totally undetectable. I even stare hard in the mirror to see them and I can't tell, so you don't need to worry about them being visible. This is the future of hair styling and anyone with thinning hair should be using them. I would qualify this by emphasising that if you have large areas of baldness they won't help, because they need existing hair to attach to. If you are well on the way to going bald they will only help for a while, but for me they work, because of the transplants. Also, if you are worried about chemicals or allergies, these are natural, which makes them better than some of the competitors. I tend to be allergic to everything, and I have zero reaction to these fibres. Dare to get them - you will not be disappointed.

Perfect coverage

I’ve tried others but this one really is the best, doesn’t clump at all and with the locking spray, stays perfectly in very windy coastal weather and rain. Only wash hair twice a week and I find mine stays looking good until next hair wash day, really impressed and especially with the applicator, makes it so easy. Haven’t tried the pool or even sea test! yet! Would prefer a slightly finer spray with the locking spray though.

Good coverage but!!!!

The product does give excellent coverage but it left my roots hard. Also it did not agree with my scalp as I couldn’t stop scratching which was a shame as the actual results were amazing. If like me you have a sensitive scalp it may not be for you.

Tried the rest now try the best

Have used a variety of different products from some of the big well know companies out there - and although they are decent - hair guru products are a step above. Great coverage and the pump is well worth purchasing .
Just one improvement that could be made - more of a fine spray from the dispenser would be helpful

Great kit but delivery was a bit slow

Love the product – the combo of the spray and applicator makes a huge difference. Took a couple of days longer than expected to arrive, but worth the wait. Customer service was quick to respond too.

Didn’t expect it to work this well

Honestly thought it would be a gimmick but I was wrong - this stuff is insane. My crown looks full again and it takes me under a minute to apply. I’ve already recommended it to three mates.

Game changer for my confidence

I’ve struggled with thinning hair for years, but this bundle genuinely changed how I feel day to day. The fibres are super natural-looking and the spray holds everything in place, even through gym sessions. The applicator gives way better coverage than shaking it by hand. Will be buying again.
